So let's start out by labeling Ethan as X
Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.
85= (3x) -21
85 -21 = 3x
60=3x
20 = x
279/34 = 8.20588235294
But if you would like to round it up it would be 8.2 or 8.21 depending on what you'd like to round it up to.
Let me know if this is what you mean. If not, I will fix it! :)
The number of cubes that Devin will need to make will be given by:
(volume of each pyramid wax)/volume of cube
volume of cube=length*width*height
=4×4×4
=64 cm³
volume of the candle=1/3π*(base area)*h
=1/3×(9×9)×10
=270 cm³
number of cubes needed
270/64
=4.21875~4.23 cubes
